Chapter: Relations and Functions Grade: 11
Question:
If f(x) = x-1/x+1, x is not equal to -1, then show that f(f(x)) = -1/x, provided that x is not equal to 0.

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
